Cd Adapco

[Jens Loco]

CDadapco was a multinational computer software company that authored and distributed applications used for computer-aided engineering, best known for its computational fluid dynamics (CFD) products.[1][2][3] In 2016 the company was acquired by Siemens Digital Industries Software.[4]

Analysis and Design Application Company (stylized "adapco") was founded in New York in 1980 as an engineering consultancy company focusing on finite element method analysis.[5] In 1987, Adapco invested in and began to collaborate with Computational Dynamics, a startup company formed by members of a CFD research group at Imperial College London. Eventually the two companies began to jointly trade under the name CD-adapco.[6]

In their 2009 annual user conference, CD-adapco announced that the company had grown 22% in 2008, and they expected similar results in 2009.[1] Professional Engineering Magazine described this as "recession-proof performance" and went on to point out that this success is especially noteworthy considering that many of the company's customers are in the automotive industry, a sector of the economy that was, at the time, suffering record low sales levels.[1] During the financial downturn of 2009, CD-adapco launched their "No Engineer Left Behind" program, which provided free STAR-CCM+ licenses and training for displaced and unemployed engineers.[7]In April 2016, Siemens acquired CD-adapco for US$970 million.

CD-adapco's legacy CFD package, STAR-CD, was praised by Renault automotive design engineers as a "world class design package". Nearly 75% of the points won during the 2005 Formula One season were awarded to drivers of cars that were designed with STAR-CD.[3]

Even in periods of major economic downturn, few customers cut back on annual licenses.[1] CD-adapco has speculated that their product's success has been partially because their application was designed from the start to simultaneously solve fluid flow and heat transfer problems. Competing products often consist of separate solvers coupled together, which requires that both be kept in agreement; a time-consuming complication that degrades accuracy.[1]

STAR-CAD is a range of product lifecycle management-embedded tools that allows engineers to perform computational fluid dynamics analysis from within their company's chosen computer-aided design environment. STAR-CAD integrates with CATIA, Pro/Engineer, SolidWorks and NX.[12]

The first release of STAR-CCM+ included the world's first commercially available polyhedral meshing algorithm.[14] The use of a polyhedral mesh has proven to be more accurate for fluid-flow problems than a hexahedral or tetrahedral mesh of a similar size (number of cells),[15] but is considerably more difficult to create.[15]

Included in STAR-CCM+ is a tool called a "surface wrapper", which "shrink wraps" a user's computer-aided design geometry, filling any holes, overlaps or cracks.[16] The company says that this feature cuts geometry preparation time down from days to minutes.[16]

CD-adapco needed its headquarters to reflect the corporate image of this successful high technology company located along Long Island's prestigious Route 110 business corridor. The four-story flat building facade was built out to give the building stepped dimensional appeal. The dated brick was updated with several thousand square feet of custom manufactured Dri-Design metal and Ombrae panels. The main vestibule was demolished and replaced with a four-sided translucent structure and two angular architectural precast concrete columns. New windows were installed on two levels of the building to match the replaced windows on the third and fourth levels.

After the facade was complete 6,900 sq.ft, Interior renovation began. The challenge was to maintain safe egress for CD-adapco's employees on the main level of the building during construction. The interior upgrade included demolition and re-construction in the selected work zones. TRITEC provided a new layout on both the first and second floors, including new partition walls, ceilings, oversized doors, custom cabinetry and millwork, finishes, lighting, an elevator retrofit, restroom renovations, and MEP upgrades.

An additional 3,420 sq.ft. of interior renovations were constructed for CD-adapco in an adjacent building for new administrative and training facilities, to accommodate CD-adapco's expanding staff and frequent visitors.

"We want our customers to have confidence and certainty in their simulations. This is fundamentally based on how close we can simulate the real performance of the final product and produce accurate results," said Senior VP of Product Management, Jean-Claude Ercolanelli. "This continued focus on realism and accuracy has allowed customers to break new ground in critical simulation work in many areas like biomedical devices ( -adapco.com/animation/heart-valve-simulation), aeroacoustics, soiling and water management ( -adapco.com/animation/soiling-and-water-management), excavation ( -adapco.com/animation/excavator-simulation), or turbulent mixing of specialty chemical products ( -adapco.com/animation/mixing-epoxy-simulation)."

Realism: Partial wrapping and extended overset mesh capabilities deliver a new level of realism in modeling more detailed systems and sophisticated motions. Details: -adapco.com/blog/james-clement/star-ccm-v906-preview-partial-wrapping-preserves-clean-surfaces

Throughput: Enhancements to the user workflow include faster setup and a new level of design exploration performance not yet seen. The new interactive tool for creation of morpher control points to drive mesh deformation and enables adjoint based shape optimization cases to be easily setup.

"These final new features allow us to deliver on the goal of STAR-CCM+ v9 series that has been focused on accurately simulating large and sophisticated models more easily, faster and in the shortest amount of time," said Ercolanelli. "We are setting the stage for our next level of development in versions 10.0x which are due out in February, June and October 2015. These releases will take simulation to a new level of understanding."

CD-adpaco the world's largest independent CFD-focused provider of engineering simulation software, support and services sent a team of volunteers to help with a Hurricane Sandy recovery/rebuild project at a home in Amityville on Saturday, May 18th. Under the supervision of team leader Steve Muzyka from the United Way of Long Island, the CD-adapco volunteers removed debris from the home and property and brought new sheet-rock into the house. They also removed dead shrubs and planted new shrubs.

CD-adapco has released the latest version of their internal combustion engine (ICE) simulation software STAR-CD and es-ice version 4.24. The latest release focuses on the performance of combustion models and model meshing.

The new version comes packaged with a pre-release of a new automated meshing tool for full geometry across the complete cycle of four-stroke gasoline and diesel engines. The automation aims to reduce mesh generation time while maintaining user control over the mesh size. When compared to existing es-ice trimmed cell meshing, the results of the analysis were comparable.

The new software generates meshes for various crank-angle positions at pre-processing. The meshes then morph over the engine stroke to optimize the mesh quality. For example, the mesh at the boundaries employs prism layers used to capture high gradient results, whereas an aligned mesh is used within the valve gap and a hexahedral mesh is used in the core of the model.

CD-adapco is well recognized in the industry for their automotive CAE software STAR-CD. While the program still maintains a large user base, many more are starting to migrate onto the larger multiphysics platform STAR-CCM+. With the industry trend to consolidate software within one CAE platform, expect to see CD-adapco starting to shift users towards STAR-CCM+. This transition might be useful for users that wish to expand their simulation capabilities, but others that work with STAR-CD as a legacy code might be more apprehensive. These new releases to STAR-CD suggest that there are still a few more years left of the product as a solo offering. However, time will tell if we will see more product consolidation at CD-adapco.

CD-adapco's industry leading simulation tool, STAR-CCM+, has a direct connection to Abaqus, delivering fully coupled, implicit two-way, fluid-structure interaction (FSI). Using direct co-simulation coupling provides efficiency and reduced overhead usually associated with data transfer through file exchanges or use of external middleware software. This co-simulation capability makes fluid-structure-thermal calculations a regular part of the engineering design process.

According to Ahmed Taha, the NCSA senior computational resource coordinator who led this extreme benchmarking project, using such a massive number of cores requires a powerful, robust MPI protocol, which was provided by Cray. CD-adapco also fine-tuned their code to improve parallel I/O.

The result of this collaborative effort over the past eight months was a steady increase in scaling, from a 105 million cell model running on 13,000 cores to a 1 billion cell model hitting the 102,000-core peak.

A privately owned company, CD-adapco has maintained 15% organic year-on-year growth over the last 5 years. CD-adapco employs 900 talented individuals, working at 40 different offices across the globe.
